LyX v2.4.0 RC4 -> Unicode in Program Listing (again...)

[Bernt Lie]

OK… I just found I had put the “-shell-escape” string in the wrong cell…

I have now changed the preferences, and inserted this string in both of the XeTeX and LuaTeX converters from LaTeX to PDF.

Now, I get the (expected) warning that using the “-shell-escape” string is *dangerous*.

Question 1:

  *   Dangerous, because LyX is more likely to *crash*, or
  *   Dangerous, because it opens up my computer to hacking??

Experience – here is some listing in LyX:

This expression is taken from a Jupyter Notebook running in VSCode (language: Julia), where the symbols are created by “\frakm + TAB \dot + TAB = m\dot + TAB v”
…and here is what it looks like when I use XeTeX/LuaTeX:

Questions 2:

  *   Could I expect a better response if I install a font that supports Unicode, and specifies this font in the fonts scheme of Listings?
  *   If I install such a font with Unicode support (e.g., JuliaMono), would that rule out using XeTeX so that I should use LuaTeX?

Question 3:

  *   If I should use LuaTeX, how can I change LyX so that issuing command Ctrl+r produces the PDF using LuaTeX?

OK -- this is the status on my on-going experimentation on Windows 11... (I hope I'm almost there):



1. I experiment with KOMA script Book

2. I have:

    * Upgraded all packages in MikTeX

    * Installed Pygments ("pip install Pygments" in Windows Prompt)

    * Figured out where the "pygmetize" script is located on my computer,

              and added location to PATH.

    * In the LyX document, Documents/Settings/Fonts, checked "use non-TeX fonts

    * In the Documents/Settings/Listings, changed "Syntax Highlighting Package" to "minted"

              [This didn't work until I set the PATH to "pygmetize"]

    * In Tools/Preferences/File Handling/Converters, added "-shell-escape" at the end

              of the Converter line:

              [This line is slightly different from the Embedded document, since that assumed pdflatex as converter).



3. STATUS:

QUESTION 1: What is wrong? I *did* envoke the “-shell-escape” flag, didn’t I?



QUESTION 2: By default, Ctrl+R is keyboard shortcut for generating PDF via pdflatex. After I chose “use non-TeX fonts”, Ctrl+R implies generating PDF via XeTeX. How can I change the set-up so that Ctrl+R implies using luatex?
